I have used WebSphere Everyplace Connection manager (WECM) to VPN into my company. I then have run the Sametime Palm client. Worked. The problem though is that if you leave the application, it disconnects. There isnt a way to keep it 'live' like you can with an instant messaging client. I deleted it because it wasnt useful. The Sametime client works much better and maintains itself in the background on a Blackberry and PocketPC device, just not on a Palm. Sucks for us.
